6x4 Propeller

This is completely experimental. Props spin at very high speeds and can be extremely dangerous.

So to test props I have printed one of my motor mounts and screwed it to a block of woord. I put the props in a push orientation with a 2200kv motor and attached the wood block to a old scale. I zero out the scale and run the prop to see how much force it exerts down in lbs. I also did a control test with a 6x4 store bought prop. This prop exerted 1.8lbs at max rpms.

Part of this adventure has been getting the print quality perfect. It took about 5 or 6 attempts but I finally can print the prop with minimal cleanup required, as seen in the photos. The second to last prop I printed only registered 0.8lbs, but also had an issue where the center hole for the shaft was a little too large and the blades did not stay aligned causing the whole thing to become unbalanced.
